Roof ventilation is ignored by most homeowners, but every cottage or home must have properly installed roof ventilation because:
• Energy bills can be significantly reduced by keeping the attic space insulated
• Without the right amount of ventilation, hot air will remain trapped in the attic, leading to the growth of black mold and moisture buildup that causes serious health issues
• Improper roof ventilation leads to ice damming during the winter, which occurs when the attic space become warmer than the outside air and leads to melting and refreezing the snow along the trough and roof, causing damage to the entire roofing system inside and out
Signs that your home is in need of roof ventilation
As a general rule of thumb, your home is in need of roof ventilation if the attic space is not consistent with the temperature outside. Other signs to look for are:
• If the rafters in your attic are frost-covered or damp during the colder months, it is a sign that your home is facing roof ventilation issues
• The unchecked growth of black mold in your attic during the warmer months
• If your energy bills are going through the roof, it is a clear sign that your home is in dire need of sufficient roof ventilation
Improper or insufficient roof ventilation will not only make your home uncomfortable to stay, but also harmful for the health of the occupants. Furthermore, it will lead to expensive roof repairs and replacements. If you are unsure whether your home requires roof ventilation, contact roofing contractors and have them assess your ventilation needs. Professionals will be able to determine if you have a proper roof or attic ventilation based on the home environment and square footage of your house.
